The Vertical Double Layer Constant Temperature Shaker is a device commonly used in laboratories in the fields of biology, chemistry, and environment, which can provide both temperature control and shaking functions. The selection of its parameters needs to be based on actual application requirements. The following are the main parameters and confirmation methods:
1. Maximum Capacity (LoadCapacity)
Confirmation method: Determine the maximum load capacity of the shaker based on the amount of sample to be processed in the experiment and the size of the container. Generally speaking, the capacity of a shaker refers to the maximum number of containers it can withstand and the maximum weight of each container. When choosing, consideration should be given to the type of container required for routine experiments (such as test tubes, flasks, culture dishes, etc.).
Common parameters: For example, a shaking table can hold up to 12 1000ml flasks or a maximum load of 10kg.
2. Shaking Speed
Confirmation method: The shaking speed is usually measured in revolutions per minute (RPM), and the selection needs to be confirmed based on the shaking frequency required for the experiment. Different experiments may require different shaking speeds, such as temperature sensitivity experiments that may require lower speeds, while cell culture experiments may require higher speeds.
Common parameters: typically ranging from 30-300 RPM, suitable for most biological or chemical experiments.
3. Shaking stroke amplitude
Confirmation method: The shaking amplitude is the vertical movement distance of the shaking table during operation, usually measured in millimeters. The selection should be confirmed based on the type of container and experimental requirements. A larger shaking amplitude is suitable for larger containers or experiments that require stronger mixing.
Common parameters: For example, the common shaking amplitude is 20mm-50mm.
4. Temperature Range
Confirmation method: The temperature control range refers to the temperature range that the shaker can stably control. When selecting, it should be confirmed according to the needs of the experiment. Some experiments require low-temperature environments, while others require high-temperature environments.
Common parameters: usually 5 ° C-60 ° C, 20 ° C-80 ° C, and even up to 100 ° C.
5. Temperature Accuracy
Confirmation method: Temperature control accuracy refers to the error range of the equipment at the set temperature. When selecting, ensure that the accuracy meets the experimental requirements to avoid the influence of temperature fluctuations on the experimental results.
Common parameters: The temperature control accuracy is usually ± 0.5 ° C - ± 1 ° C.
6. Control System and Display
Confirmation method: When selecting, it is necessary to confirm the type of control system, such as digital display, touch screen control, PLC control, etc., to ensure that the operating interface is intuitive and easy to adjust.
Common parameters: digital display, PID temperature control system, with high-precision temperature control.
7. Shaking Type
Confirmation method: The oscillation mode of the shaker can be divided into linear oscillation and circular oscillation. Linear oscillation refers to the linear motion of a shaking bed surface, while circular oscillation refers to rotational motion. When choosing, it is necessary to consider the type of container used in the experiment and the desired mixing effect.
Common parameters: linear oscillation, circular oscillation, or both.
8. Noise Level
Confirmation method: When selecting, the quiet requirements of the laboratory environment should be taken into account, especially for experiments with long-term oscillations. Equipment with lower noise levels can help improve the experimental environment.
Common parameters: Typically, the noise level is 50-60 decibels.
9. Dimensions
Confirmation method: When selecting, consider the size of the laboratory space to ensure that the equipment can adapt to the laboratory layout. At the same time, it is necessary to ensure that the sockets, wiring, power supply, and other equipment are arranged reasonably to avoid unnecessary space waste.
Common parameters: The equipment size is generally 60cm × 60cm × 70cm, etc.
10. Power Supply Requirements
Confirmation method: Power requirements are usually related to the power and operating voltage of the equipment. Select the appropriate power source type and voltage based on the electrical conditions of the laboratory.
Common parameters: The general voltage is 220V or 110V, and the power range is 200W-800W.
summary
When confirming the parameters of a large capacity vertical double-layer constant temperature shaker, comprehensive consideration should be given to the sample quantity, container type, temperature control range, shaking speed, and other requirements of the experiment. In addition, the convenience of operation, the safety of equipment, and the ease of maintenance are also important considerations when choosing. Choosing a suitable shaker can improve experimental efficiency and ensure the stability and accuracy of the experiment.
